Do you know what mixture it is talking about?
An c.ionic bond forms when a cation transfers its extra electron to an anion who needs it.
For example compound magnesium chloride (MgCl₂) has ionic bond (<span>the </span>electrostatic attraction<span> between oppositely charged </span><span>ions)</span>. Magnesium transfers two electrons (became positive cation) to chlorine (became negative anion).

Answer:
Concentration of original solution = 1.66
Explanation:
We know that
We have given concentration of NaOH = 0.1678
Volume of NaOH = 19.88 mL = 0.01988 L
So moles of NaOH = volume x concentration of NaOH
= 
Moles of 
in 10 mL of diluted solution = 1/2 x moles of NaOH
= 
x 0.00333 = 0.00166 mol
Moles of in 25 mL of original solution
= moles of H2SO4 in 250 mL of diluted solution
= 
x 0.00166 = 0.0415 mol
Concentration of original solution = 
=
